| 摘 要： | 以常规３：１式为对照，研究改良３：１式棉麦套作共生期田间小气候效应及对小麦生育和产量的影响。结果表明，两种方式的田间小气候变化差异明显，小麦株高、穗长和千粒重等性状差异不明显。改良３：１式的小麦灌浆速率小于常规３：１式，结实小穗和穗粒数也少于常规３：１式，但穗数明显多于常规３：１式，产量也高于常规３：１式（相差４６２ｋｇ／ｈｍ￣２）。

| Abstract: | Field microclimate effeets of the improved 3:1wheat-cotton intercropping pattern and its influ -ences on wheat growth and yield were studied,using the common 3:1 pattern as control.The resultsshowed significant differences between the two patterns for field microclimate effects.Wheat height,spike length and thousand kernel weight of the two paterns had little difference,Wheat grain filling in-tensity of the improved 3:1 pattern was less than that of the common 3:1 pattern,so were the fer-tile spikelet number and the kernel mumber per spike. But spike number and yield per hectare of the former were much higher than those of the latter(yield of the former was 462kg per heetare higher than that of the laltter.) |
